Check out two of the Winnipeg Warming Hut competition winners

Every year there is an international competition to design warming huts on the Assiniboine River in Winnipeg, where designers are asked to "push the boundaries in terms of inspiration, design, and materials used."

Nuzzles

Another winner was Toronto's RAW Design Designboom shows their Nuzzles. warming huts built out of pool noodles stuck onto little geodesic domes. Not quite as minimalist as the Red Blankets but probably a bit warmer when you get inside.
